What is the solution of the equation 8/5 x = −10 ?(1 point)
To find the solution to the equation 8/5 x = -10, we can multiply both sides of the equation by the reciprocal of 8/5, which is 5/8.
(8/5) * (5/8) x = -10 * (5/8)
1x = -50/8
Simplifying the right side of the equation, we get:
x = -50/8
This can also be simplified as:
x = -25/4
Therefore, the solution to the equation 8/5 x = -10 is x = -25/4.
(8/5) * (5/8) x = -10 * (5/8)
1x = -50/8
Simplifying the right side of the equation, we get:
x = -50/8
This can also be simplified as:
x = -25/4
Therefore, the solution to the equation 8/5 x = -10 is x = -25/4.

2a = 13
2 a equals 13
a + 1/2 = 13
a plus Start Fraction 1 over 2 End Fraction equals 13
1/2a = 13
To represent Justin's age, let's use the variable "a." According to the problem, Kendra's age is half of Justin's age, and Kendra is 13 years old. This means that Justin's age can be expressed as "2a" since it is twice Kendra's age.
So, the equation that represents Justin's age is 2a = 13.
So, the equation that represents Justin's age is 2a = 13.

h/2 = 3.5
Start Fraction h over 2 End Fraction equals 3.5
h/14 = 3.5
Start Fraction h over 14 End Fraction equals 3.5
h/3.5 = 2

3.5h = 14
To find the total number of hours (h) Cooper will volunteer at the community food bank, we know that he will work 3.5 hours every day for two weeks.
Since there are 7 days in a week, Cooper will work 3.5 * 7 = 24.5 hours in one week.
To find the total number of hours for two weeks, we can multiply the hours worked in one week by 2:
24.5 * 2 = 49
Therefore, the equation that represents the total number of hours Cooper will volunteer at the community food bank is 3.5h = 49.
Since there are 7 days in a week, Cooper will work 3.5 * 7 = 24.5 hours in one week.
To find the total number of hours for two weeks, we can multiply the hours worked in one week by 2:
24.5 * 2 = 49
Therefore, the equation that represents the total number of hours Cooper will volunteer at the community food bank is 3.5h = 49.
wrong
Apologies for the mistake. Let's correct it.
Cooper will volunteer for two weeks, and he will work 3.5 hours every day. To find the total number of hours (h) that Cooper will volunteer at the community food bank, we multiply the number of days in two weeks (14 days) by the number of hours worked each day (3.5 hours/day):
h = 14 * 3.5
Simplifying this equation:
h = 49
Therefore, the correct equation representing the total number of hours Cooper will volunteer at the community food bank is h = 49.
Cooper will volunteer for two weeks, and he will work 3.5 hours every day. To find the total number of hours (h) that Cooper will volunteer at the community food bank, we multiply the number of days in two weeks (14 days) by the number of hours worked each day (3.5 hours/day):
h = 14 * 3.5
